Triaxial Dome Camera with Light Blocking Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dome-type surveillance cameras require complex adjustments to change the surveillance area, and the hemispherical cover's transparent window causes diffused reflection, degrading image quality.
Innovation Solution
A triaxial dome-type surveillance camera with a triaxial rotary body for easy angle adjustment and a diffused reflection preventing device on the upper cap to block reflected light, allowing the camera module to be tilted or rotated without tools and improving image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the hemispherical cover is used with a transparent window part, then the surveillance area can be visually recognized, but external light is diffusely reflected in the window part, degrading image quality
Solution Approach 1:
The patent extracts the harmful diffused reflection from the optical path by introducing a light blocking structure that selectively removes reflected light while preserving the transparent window's primary function of allowing light transmission for surveillance
Solution Approach 2:
The patent introduces an intermediary light blocking structure positioned between the window and camera module that mediates the optical interaction, blocking harmful diffused reflection while allowing useful light transmission for image capture
2Ease of operation
If the hemispherical cover is fastened to the base with multiple screws, then the cover is securely fixed, but the cover has to be separated for adjustment, increasing the time required to readjust the camera
Solution Approach 1:
The patent segments the cover assembly into a detachable cover portion and a base portion with independent adjustment mechanisms, allowing the camera module to be adjusted without removing the entire cover
Solution Approach 2:
The patent introduces a dynamic adjustment mechanism that allows the camera module to be tilted or rotated while the cover remains attached to the base, transforming the static fixed-cover design into a dynamic adjustable system
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy adjustment of the camera's capturing angle and prevents diffused reflection, enhancing image quality by allowing the camera module to rotate freely and blocking external light reflections.
Implementation Method 1
a diffused reflection preventing device provided on an upper cap to which a camera module is coupled so as to prevent diffused reflection of light that degrades quality of a captured image
